#### Worksheet Overview

When two or more options occur, there are multiple possible outcomes.

For example, when you go to the cinema you have the following popcorn options:

Sweet             Salty

Small = Medium =Large =

So the possible outcomes are:

small, sweet

small, salty

medium, sweet

medium, salty

large, sweet

large, salty

There are 6 possible outcomes.

So the probability of selecting a medium, salty popcorn is 1/6

Let's have a go at some questions listing outcomes and finding probability.

Remember when listing outcomes to make sure we make logical, organised lists to ensure we don't miss any!
